“He did a great job picking the team up when Unai left and we all have 100 per cent respect for him as a man and a coach.
“I know I’ll be facing him on the touchline in the future.”
Meanwhile, Arsenal technical director Edu declared: “We’re really sad to see Freddie leave as we know how much he loves Arsenal.
“However, we know he has had various opportunities over the last 12 months and stuck to the job at Arsenal.
“Now he has the opportunity to consider other options, and it makes sense for his career at this time.
“Freddie has made a huge contribution in his coaching role, most importantly when he led the team during that difficult period between Unai’s departure and Mikel’s appointment.
